One object of this invention is to devise nov-el construct-ion ef a. polishing device wherein the casingandthe filler are constructed and secured together in a novel manner A further object of this invention is to devise i nevel fillerhaving au outer ycovering which will present an attractive appearance, and an inner strip of cheaper material. The cover and right to left or from side to side. The cover and strip are sewed .together and spaced vslots are provided between the sewing and the top folded edge. These slots arev adapted lto` receive Ia locking member to secure the-filler within a back vsupport adapted to be received in a casing'which latter is adapted to be grasped by the hand of the user.

W ith the above and other objects in View, as will. hereinafter more clearly appear, my invention eoinprehends a novel brush consisting of a novel construction of a casing,

a novel construction of a filler, a novelback4 support7 and na. novel locking member eooperating with thel iller,-baek support and easing'in a novel manner to secure the parts in assembled condition. e L

'1t further comprehends a novel backing for the filler which is adapted to cooperate with the locking member.

lt further comprehends a novel brush wherein theIlocking member and easing co.- operate in such be moved which my invention consist can be variously arranged and organized and my invention is notlimited, to the exact arrangement and organization of these instrumentalities as herein set forth and claimed. .v

Referring to the drawings The grasping portion of the polishing device is formed from a lblank 1 having longitudinally weakenedv lines 2 at each side,

spaced from its rmarginal edges so as to form the sides?) when bent downwardly, andthese sides are provided with the transversely ex.-

tending slots 4 which are adapted tofreceiver the tongues 5 of the end extensions 6, which ofthe vblank and arearranged at each end i vin pairs. i

the notches or serrations 7. When the blank uis' folded, as shown lin Figures lla-nd 2, it forms a casing'- and the sides 3 rareloclred.

in positienby the tongues 5 extending into the slots 4.( e Y 8 designates the filler which is formed of an outer 'strip of fabric 9 which is folded latter'fex'tend outwardly beyond the'body upon itself and between the foldis a strip .of material 10-'which canbe of inexpensive ina-terial rsuch asv for example,. felt. The

strips '9 and 1() arethe-n folded together and sewed togetheig,spacedv slots are made between'the sewing and top folded edge, as will best be understood by reference to Figures 2, 4, and 9,Y a spring strip 14 is then passed through' said slots and the filler is then inserted into a holder 11 which Con'- sistsof arrectangular box shaped vmember ope-nat its'bottom and provided in its sides and top with apertures 12V which are for ventilation, ,and .havingA in its ends, slots 13.

The ends of this holder 11 are provided with the slots 13 through which is adapted to pass a locking member 14k of novel constructiom said locking member also passing through the slot-s 15 formed by the end extensions 6. `This locking member 14: consists of a flat strip of spring material, preferably metal, they ends of which are deflected c engage with the juxtaposed notch 0r serration of the notches or serrations 7. At each end, this locking member 14 has detachably connected therewith a grasping handle 17 preferably in the form of a ring as illustrated. One ring beingremoved, this locking member 14 passes through ,slots 18 in the filler. These slots are spaced between the seu/ing and the top folded edge of the filler.

The filler as an article of manufacture consists of the strips 9 and 10 which are folded from left to right or from right to left so as to form a lapped construction. The loclring strip 14 is passed through the slots 18 in the filler and the slots 13 in the back sov that the filler is new assembled with respect to its back 11.

rIhis back with the liller and the locking member 14 are then inserted into the casing or grasping portion. The locking member passes through the slots 15 at the end of the casing. As before explained, the locking member' 14 has a twist set in it so that the top locking portion 16 will engage one of the notches 7 at the left hand end of the casing, and the top iiange 16 at the opposite end of the locking member will engage the juxtaposed notch 7 at the top, at the right hand end of the casing. The lower flanges contacting with the smooth edges ofthe slet 15 in the extensions 6, contribute to retain the top Aflanges in locking engagement with the walls ofthe notches.

After the filler has become worn, the filler and its back, together with the locking member, may be moved outwardly, relatively to its easing, by the operator taking hold of the rings 17 and slightly twisting or turning the ends of the locking member 14 in a direction to disengage the locking'flanges from their notches. rllhe locking member, back and filler can then be moved outwardly as a unit of structure to engage an outer notch so that the filler can be made short and stili', or long and soft, or can be used until it is practically worn out.

' The casing may, if desired, be provided.

with the eut out portions, such as, for example, they cut outs 19 of any desired contour, as seen 1n Figures 1 and 6, 1n order to reduce the weight of the brush and provide for ventilation and a better hand hold.

It will be apparent that in accordance with this invention the filler can be moved outwardly from the casing until it is practically worn out, and when worn out the old filler can be readily removed and a new ller inserted, se that the casing, locking member, and back for the filler can be used for a long period of time, and the filler can be replaced as it becomes necessary.

Having thus described my invention wha 'l claim as'new and desire to secure by Let` till ends, the edges of which are provided with p vertically disposed notches, an open back adapted telit into said casing and having slots at its ends` a ller in said back comprising a plurality of folded strips, and a spring locking strip having a twist and having at its ends side yflanges to engage desired notches said twist providing a spring tension, said lockingmember passing through said filler and said back.

A filler for brushes con'iprising an outer strip egt-material folded upon itself1 and an inner strip of material sewed within said` fold, saidfo'lds having spaced slots between t ie sewing and their top, and said strips being' folded laterally so. that the free edges l the strips formV the polishing face of the 'i er.

4. A polishing device comprising a casingy open at its bottom and having a slot at each end opening through its bottom edge and having one wall of each slot provided with spaced notches, a back having a slot at each end, a laterally folded filler within said back and having slots in alignment with the end slots in said back, a locking member passing through the end slots in said back and the slots in said filler and slidable into said casing slots and having deflected portions to engage desired notches at the ends of the casing which latter overhangs said filler to stiffen it, whereby when the filler and bacl: are adjusted outwardly of the casing the polishing device will be soft and flexible, and when secured a further distance into the casingfthe filler is stiffer and less flexible.
